This could be that the addition of chelating ligand complexed both metallic species retarding sulfidation of both metals, hence lowering the HDS activity. Studies show that it is possible for the citric acid to complex with both promoter and an active metal (Mo), and this might result in the formation of molybdenum dimers, trimers and tetramers which are difficult to sulfide.

A strong linear relationship between dNBR and stem fire severity (r2 = 0.69, p < 0.001) confirmed the accuracy of dNBR as a measure of fire severity in Afrotemperate forest. In the fire investigated, 4 628 ha of Afrotemperate forest burnt of which 67% burnt at low severity, 21% at medium severity and 12% at high severity. The dNBR values associated with fire severity categories were comparable between Afrotemperate and North American forests, suggesting that dNBR values are relatively standard across forest types. Information on the distribution of fire severity facilitates investigation of further questions regarding past and future fire regimes and the fire ecology of Afrotemperate forest. The post-fire survival rate of Afrotemperate forest trees was 45% which is comparable to that in coniferous forests of North America but lower than that in temperate forests of Australia and Portugal and the neighbouring dune thicket which shares several species with Afrotemperate forest. Fire severity had a significant negative effect on survival and tree size a significant positive effect. Total variance explained by the model (for species collectively) was 40.8%, of which fire severity and tree size combined explained 13.2%, and species as random factor, 27.6%. Respective tree species showed differential survival responses – four species showed high survival (> 60% of individuals), while five species showed low survival (< 40%). This study was the first post-fire assessment of the resprouting ability of Afrotemperate forest trees and a third of the trees surveyed (for species collectively) resprouted from the stem. This suggested that resprouting from the stem is a primary means of post-fire recovery in Afrotemperate forest trees, in contrast with previous assertions that several common canopy species, including Podocarpus latifolius, Afrocarpus falcatus, Scutia myrtina, Scolopia mundii and Rapanea melanophloeos, are unable to resprout. Varying resilience to fire among species supports previous suggestions that fire affects species’ composition and diversity in these forests and calls for careful management of fire regimes in the face of global change.]]> Thu 09 Jun 2022 16:02:39 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:71823 Thu 07 Mar 2024 09:50:42 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:70969 Thu 07 Mar 2024 09:01:13 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:44888 Thu 04 Nov 2021 11:21:30 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:44890 Thu 04 Nov 2021 09:42:53 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:46022 Thu 03 Feb 2022 13:55:30 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:47656 Sat 05 Mar 2022 12:11:37 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45691 Mon 31 Jan 2022 13:44:08 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:52374 Mon 14 Nov 2022 08:43:49 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:46577 Mon 14 Feb 2022 15:26:49 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:46541 Mon 14 Feb 2022 12:03:49 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:46517 Mon 14 Feb 2022 10:36:11 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:52014 Mon 13 Jun 2022 15:11:00 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:52017 Mon 13 Jun 2022 12:24:52 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45690 Mon 11 Jul 2022 11:36:49 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:44907 Mon 08 Nov 2021 14:50:01 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:44906 Mon 08 Nov 2021 12:31:49 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:44905 Mon 08 Nov 2021 12:03:39 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:44897 Mon 08 Nov 2021 10:04:18 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:44898 Mon 08 Nov 2021 09:43:48 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:44894 Mon 08 Nov 2021 08:56:05 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:58191 Mon 07 Nov 2022 11:07:45 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:44869 Fri 29 Oct 2021 11:21:35 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:44874 Fri 29 Oct 2021 11:18:24 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45683 Fri 28 Jan 2022 10:32:56 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45686 Fri 28 Jan 2022 09:28:09 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:69320 Fri 27 Oct 2023 12:29:26 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:69318 Fri 27 Oct 2023 11:22:03 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:69316 Fri 27 Oct 2023 11:15:40 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:69314 Fri 27 Oct 2023 11:01:17 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45132 Fri 12 Nov 2021 09:30:45 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:46477 Fri 11 Feb 2022 14:49:33 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:66484 Fri 11 Aug 2023 11:43:05 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:52000 Fri 10 Jun 2022 12:04:20 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:51996 Fri 10 Jun 2022 11:50:14 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:51993 Fri 10 Jun 2022 10:33:13 SAST ]]>
